Hg2+ selective fluorescent and colorimetric sensor: its crystal structure and application to bioimaging.
A Hg(2+)-selective rhodamine 6G derivative bearing thiolactone moiety was synthesized, and its crystal structure with Hg(2+) is presented to explain the binding mode. In addition, highly selective "off-on"-type fluorescent change upon the addition of Hg(2+) was also applied to bioimaging.
